Self-priming domestic hydrofor Wilo-Jet HWJ 202-EM/2-2 4265550

Domestic water booster – reliable water supply

This Wilo-Jet HWJ 202-EM/2-2 booster set is a complete solution for supplying water to single-family homes, gardens and farms. The device combines a self-priming pump with a 20-liter pressure tank, providing stable water pressure and reducing the frequency of pump starts. This translates to a longer device life and quieter operation.

Construction and application

The booster is designed for drawing water from wells, tanks or other sources where the water level is up to 8 meters below the pump level. The construction based on high-quality materials, such as stainless steel, guarantees corrosion resistance and long-term use, even with occasional downtime. The 20-liter pressure tank with EPDM membrane minimizes pressure fluctuations and protects the pump from frequent starts. The whole is ready to connect – just connect the power and hoses.

Key features and benefits

• Self-priming: The pump automatically draws water, even after a long period of inactivity – it does not require manual filling.
• Pressure tank: Provides stable water pressure in the installation and limits the number of pump starts, which extends its life.
• Durable construction: The pump body made of stainless steel ensures corrosion resistance and long-term reliability.
• Motor with thermal protection: Protects the motor from overheating and damage during intensive operation (in the single-phase version).
• Ready for installation: The set includes all the necessary elements for electrical and hydraulic connection, which facilitates installation.
• Reduction of water hammer: The diaphragm tank dampens sudden pressure changes in the installation, protecting pipes and equipment from damage.
• Performance: The pump provides a capacity of up to 4.5 m³/h and a maximum head of 36.55 m, allowing for efficient water supply even in larger buildings.
